Quantifying Body Composition and Liver Disease in Children Using Free-Breathing MRI and MRE

Magnetic resonance imaging (MRI) is a non-invasive imaging technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the body.

Magnetic resonance elastography (MRE) is a non-invasive imaging technique that uses a gently vibrating transducer in combination with MRI to create detailed images and maps of the mechanical properties, such as stiffness, of tissues within the body.

The prototype device is provided to the investigators by Mayo Clinic under a Materials Transfer Agreement (MTA). The device is being used to promote comfort in the pediatric population; no formal data collection for regulatory submission is planned. The prototype device is smaller, softer, and more flexible than the commercial device and will be used where indicated by the subjects' size.
